Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems face challenges in achieving sensing tasks with the assistance of another user equipment (UE) in sidelink (SL) scenarios, particularly in establishing connections and ensuring that the UE can interact with the network for integrated sensing and communication operations.
Innovation Solution
A communication method and apparatus that enable a first terminal device to request a second terminal device to perform a sensing task, and facilitate the discovery and connection of another UE capable of performing the task, by exchanging specific information and identifiers to establish network interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a terminal device requests another UE to perform sensing tasks via sidelink, then sensing capability is enhanced, but connection establishment complexity increases
Solution Approach 1:
The network device acts as an intermediary to facilitate the discovery and connection between the first terminal device and the second terminal device. The network device transmits second information indicating to the first terminal device to discover another UE capable of performing the sensing task, thereby simplifying the connection establishment process while enabling enhanced sensing capability.
2Productivity
If UE discovers another UE capable of sensing tasks, then sensing task execution is improved, but information exchange overhead increases
Solution Approach 1:
The system performs preliminary discovery and capability indication before the actual sensing task execution. The network device transmits second information in advance indicating to the first terminal device to discover another UE capable of performing the sensing task, so that when the sensing task needs to be executed, the suitable UE has already been identified and connected, reducing the information exchange overhead during task execution.
